Definitions
- the present application relates to methods for coating metallic surfaces to prevent specks on zinc-containing metallic surfaces using a silane additive in an aqueous cleaning composition, in an aqueous rinse liquid and / or in an aqueous activation composition.
- Stipes are white or bright spots on the metal surface that look like a crater under the microscope. In crass situations, the crater-shaped pebbles can even protrude about 1 mm high from the metallic surface, the zinc-containing coating, for example, a hot-dip galvanizing inside the crater-shaped lip more or less dissolved.
- FIG. 1 shows a particularly large bar in the scanning electron micrograph on a galvanized and then zinc-phosphated metallic surface, which protrudes about 1 mm high from the coated surface and in the interior of which the galvanization is largely resolved. Staining may be the starting point for more damage from corrosion as the protective zinc or zinc alloy layer is severely damaged at the lip and may be the starting point for more damage from delamination of the overlying coating. Therefore, a single stem disturbs already, and therefore specks in industrial practice are to be avoided altogether.
- the reworking is done in particular by the fact that these parts in the area around the damaged area, for example, by grinding or sandblasting and possibly processed to the metallic surface and then again be compensated eg by aftertreatment such as by phosphating and with one or more coats. Due to the fact that such repairs often occur in a line of body coating in the automotive industry and are usually performed by hand, the time and effort is very high.
- Stippings are often recognized only at the end of a treatment line after the conversion coating or even after the further coating with an electrodeposition paint, powder coating or primer or palpated with the hands as bumps. Only under certain conditions may larger specks on cleaned metallic surfaces, on rinsed metallic surfaces, on activated metallic surfaces, or on conversion coated e.g. phosphated metallic surfaces are detected when the treated substrates are removed from the bath.
- a typical treatment line for phosphating may include at least one cleaning zone with an aqueous cleaning composition, at least one rinse zone with an aqueous rinse, and optionally at least one pretreatment zone prior to phosphating with an aqueous activation composition A) or B), and then zones for phosphating and comprise at least one new rinse with an aqueous rinse liquid, optionally before at least one zone for at least one finish.
- Another typical treatment line may be, for example, at least one cleaning zone with an aqueous cleaning composition, at least one rinse zone with an aqueous rinse and at least one zone for the treatment or pretreatment with a silane-containing conversion conversion aqueous composition and optionally thereafter at least one rinse zone with an aqueous rinse and optionally also include zones for at least one coating.
- a typical treatment line may include, for example, at least one cleaning zone with an aqueous cleaning composition, at least one rinse zone with an aqueous rinse liquid, and at least one zone for treatment or pretreatment with an aqueous composition for conversion coating and optionally thereafter at least one rinse zone with an aqueous rinse liquid and optionally at least include a zone for at least one finish.
- a zone is in practice equivalent to a level.
- EP 0 224 190 A2 describes methods of activating metal surfaces between the purge / purge and zinc phosphating steps using aqueous alkaline solutions containing titanium ions and phosphate ions in which the activating solutions are adjusted to a pH of 8 to 10 and additionally disodium tetraborate and / or others soluble alkali or alkaline earth metal borates added.
- EP 0 264 151 A1 discloses processes for producing phosphate coatings on steel and galvanized steel composite parts by alkaline cleaning, rinsing with aqueous rinse and zinc phosphating, in which the cleaned composite parts are rinsed with a rinse bath containing at least 0.2 g / L alkali borate, at least 0.1 g / L contains alkali silicate and at least 0.05 g / L alkali nitrite.
- DE 102008054407 A1 teaches methods of phosphating metallic surfaces wherein the metallic surfaces are treated with an aqueous colloidal phosphating agent and titanium prior to phosphating and wherein the activating agent contains at least one water-soluble silicon compound having at least one organic group.
- aqueous cleaning composition When metallic surfaces are to be coated and not recently hot-dip galvanized, it is common practice to first clean, especially degrease, the metallic surfaces in an aqueous cleaning composition.
- an acidic, neutral, alkaline or strongly alkaline cleaning composition it is possible in particular to use an acidic, neutral, alkaline or strongly alkaline cleaning composition, but optionally also an acid pickling composition.
- the aqueous cleaning composition may contain, in addition to at least one surfactant, optionally also a scaffold or / and other additives such as e.g. Complexing agent included.
- the water optionally also containing an additive dissolved in water, such as e.g. a nitrite may be added.
- a phosphating phosphating solution which may be followed by activation, may contain in addition to the cations and in addition to a content of orthophosphate, in particular a content of condensed phosphate, nitrate, fluoride, complex fluoride, organic Polymer and / or accelerator such as accelerators based on nitrite, chlorate, peroxide or / and nitro compound such as nitroguanidine included.
- aqueous phosphating solutions e.g. Zinc manganese nickel phosphating solutions
- silane-containing solutions contain, in addition to at least one silane, silanol or / and siloxane, optionally also an addition of organic polymer / copolymer, cations, fluoride, complex fluoride, silicate or / and other additives such.
- the treatment or pretreatment with a conversion composition may be followed, if necessary, by a rinsing with water followed by a treatment with a rinsing solution, which may optionally be followed by rinsing with water.
- the first lacquer layer after a pretreatment is an electrodeposition coating with an electrodeposition paint such as e.g. a cathodic electrodeposition paint (KTL, e-coat), a primer or a powder coating used.
- the object is achieved by using a silane additive to prevent specks on zinc-containing metallic surfaces 1.) in an aqueous cleaning composition, 2.) in an aqueous rinsing liquid, the a) before cleaning, the b) in the middle of several cleaning zones, c) immediately after cleaning and / or d) used as a liquid for cooling, or / and 3.) in an aqueous activating composition, the content of each of at least one silane, silanol or / and siloxane in at least one of these aqueous Compositions in the range of 0.001 to 5 g / L calculated on the particular silane.
- the silane is referred to herein as the starting compound of the reaction chain, e.g. from silane via silanol to siloxane.
- silane or “silane additive” includes silane, silanol or / and siloxane - as will be explained in more detail below.
- the panels were first cleaned with an aqueous cleaning liquid Gardoclean ® 854/5 Chemetall GmbH at a pH value of 10.5 by dipping at 60 ° C for 10 minutes and immediately thereafter rinsed with tap water for 30 seconds by immersion at room temperature. Activation was carried out thereto subsequently with an aqueous activating composition A), with 3 g / L activating concentrate Gardolene ® V 6559 from Chemetall GmbH had been added in liquid form to deionized water before, with stirring.
